The invention relates to an internal washing device for containers including a base with a structure including telescopically extendable sections and in which at least one cleaning element is housed. The base includes a drive shaft, each section includes at least one toothed longitudinal segment configured to engage with at least one pinion fastened to the drive shaft. The sections include a push pawl. The initial section incorporates a support element on the forward end, and the additional sections incorporate a pull pawl and a recess for the fastening of the corresponding push pawl, such that the drive shaft has the ability to operate all the sections without needing to move.

There is provided an apparatus, system, and method of treating a condition in an enclosable environment. The method includes adding water and a formulation into a container and closing the enclosable environment with the container there inside. The water and formulation are agitated via a magnetic impeller, thereby causing a release of a gaseous cleaning agent from the formulation. An air-borne spray exiting from the container spreads throughout the enclosable environment to contact the air and surfaces to be cleaned, thereby decontaminating, and removing malodor from within the enclosable environment. The enclosable environment is maintained closed for an effective time period while the cleaning agent treats the enclosable space.

A manually-operated trailer wash apparatus for washing an interior of a trailer includes a frame with a handle configured to be manually pushed by a human operator and front and rear wheels. Rotatable couplings are disposed between each of the wheels and the frame to rotate the wheels in response to the manual pushing of the handle. A conduit is coupled to the frame and extends transversely across a direction of travel of the apparatus. The conduit has a plurality of nozzles to pressure wash a surface on which the apparatus travels. The conduit receives pressurized fluid from a hose and pump system.

Systems, devices, and methods for passing railcar tank cleaning systems through the opening and mounted to existing manways. The invention can extend horizontally more than 25 feet and clean rail cars up to and beyond approximately 102 inches in diameter for manual, automated, or semi-automated programmable railcar tank cleaning systems, devices and methods for providing safe and efficient methods for breaking up oil, tar, chemical, radioactive, hazardous, or any other liquid, solid, or sludge waste inside rail tank cars and the like with nozzles which utilize fluid jets to break up, liquefy, and motivate tank material. The programmable railcar cleaning system can be a standalone, independent unit or integrated into new designs and/or existing systems. Simplified programming and user interface allow an operator to remotely operate the system. The various capabilities of this invention allow cleaning in a quicker and more efficient manner. The system is hydraulically controlled and can work in the presence of flammable vapors and dust.

There is provided a system and method of cleaning surfaces of an enclosable environment of a contamination comprising a microbial and viral load. The method includes the steps of sealing the enclosable environment and placing water, and a solid or gel pack, into a container and generating a vortex the container by rotating an impeller. The agitation causes the solid or gel pack to release a gaseous cleaning agent. An air-borne spray exiting from the container spreads throughout the enclosable environment to contact the surfaces to be cleaned within the enclosable environment. The enclosable environment is maintained closed for an effective time period while the air-borne spray dwells on the surfaces to eliminate or substantially reduce the load of the contamination.

An autonomous vehicle includes interior sensors including a camera, IR camera, electro-chemical sensor, humidity sensor, and temperature sensor. Initial and final outputs of these sensors are captured for a trip conveying one or more passengers. If changes in the outputs of the sensors are detected, whether the final outputs of the sensors are acceptable may be evaluated. In some embodiments, an aggregation of the outputs is evaluated and found unacceptable even where individual outputs are acceptable. Outputs may be presented to a dispatcher to confirm that the outputs are unacceptable. If the outputs are found to be unacceptable, the vehicle may be autonomously driven to a cleaning station. Personal items may be identified in camera outputs and alerts generated in response.

A cleaning element includes a fiber assembly having a plurality of fibers extending in a predetermined direction and a nonwoven fabric provided on the fiber assembly. A first fusion bonded part extends in a cross direction traversing the predetermined direction to fusion-bond the fiber assembly and the nonwoven fabric, and a plurality of second fusion bonded parts is provided discontinuously in the cross direction to fusion-bond the fiber assembly and the nonwoven fabric. Each of the second fusion bonded parts has a first area and a second area. A length in the predetermined direction from the first fusion bonded part to the first area is different from a length in the predetermined direction from the first fusion bonded part to the second area.

The disclosed technology provides solutions for facilitating automated cleaning of an autonomous vehicle (AV) and in particular, for identifying objects and maintenance areas within an AV cabin. A process of the disclosed technology can include steps for collecting sensor data representing a cabin of an autonomous vehicle (AV) using an optical sensor disposed on a robotic arm, identifying one or more objects represented by the sensor data, and determining if the cabin of the AV can be cleaned using one or more tools associated with the robotic arm based on an identification of at least one of the one or more objects. Systems and machine-readable media are also provided.

The disclosed technology provides solutions for localizing a robotic arm to facilitate entry into and cleaning of an autonomous vehicle (AV) cabin. A process of the disclosed technology can include steps for locating a door handle of an AV, actuating the door handle to open a door of the AV, and positioning a robotic arm inside a cabin of the AV. The process may further include steps for collecting image data representing the cabin using an optical sensor disposed on a distal end of the robotic arm, identifying one or more features within the cabin based, and localizing the robotic arm within the cabin of the AV. Systems and machine-readable media are also provided.

A vehicle purification device includes: a determiner (45, 300) configured to determine a state of a vehicle; a necessity determiner configured to determine whether purification of the vehicle is necessary according to the state of the vehicle determined by the determiner; a possibility determiner configured to determine that the purification of the vehicle is possible using equipment of the vehicle when the necessity determiner determines that the purification of the vehicle is necessary; and a device controller (190) configured to perform a predetermined operation so that the purification is performed by another unit different from the equipment of the vehicle when the possibility determiner determines that the purification of the vehicle is not possible.
